Abstract (en)
[origin: WO2014185957A1] A method for treatment of a carbonaceous feedstock such as coal or black liquor is disclosed. The method comprises heating a mixture of the carbonaceous feedstock, with or without a solubilizing agent, water, and an oxidizing agent to solubilize and oxidize carbonaceous materials. In case of oxidation of black liquor, at least one organic compound comprising from about 2 to about 20 carbon atoms may be obtained. The reaction products may be chemically or physically separated, recycled to the heating step and/or subjected to microbial digestion in order to generate one or more desirable products from the carbonaceous feedstock.
